Why I did it
Prevent from i2c bus to get locked.
How I did it
Add sysfs driver to access ioport.
Command to reset i2c mux:
echo 1 > /sys/devices/platform/as9716_32d_ioport/i2c_mux_rst
Command to bring i2c mux out of reset:
echo 0 > /sys/devices/platform/as9716_32d_ioport/i2c_mux_rst

Why I did it
Old fan drv will be build fail under kernel 5.10. It get below error message.
/sonic/platform/broadcom/sonic-platform-modules-accton/as7312-54xs/modules/accton_as7312_54x_fan.c:483:5: error: implicit declarat ion of function 'set_fs'; did you mean 'sget_fc'? [-Werror=implicit-function-declaration]

sget_fc
How I did it
These code is old design and they are not needed currently. So remove them.

Add needed code to pddf_custom_psu.c to deal with multi PSU and get SN.
How to verify it
Plugin new PSU (3Y) and test,
```
root@sonic:/sys/bus/i2c/drivers/psu/9-0050# cat psu_serial_num
S0A000X601919000013
root@sonic:/sys/bus/i2c/drivers/psu/9-0050# cat psu_model_name
YESM1300AM
root@sonic:/home/admin# pddf_psuutil mfrinfo
PSU Status Manufacturer ID Model Serial Fan Airflow Direction
PSU1 NOT OK 3Y POWER YESM1300AM S0A000X601919000007 exhaust
PSU2 OK 3Y POWER YESM1300AM S0A000X601919000013 exhaust
```
